Essential videos of 2025

44 of the 107 videos uploaded in 2025 were judged high on "words matter": the ideas are the point of the video, so reading or watching for the argument pays off — a reading guide, not a best-of list. Each entry gives the thesis (with a link to where the argument starts) and one line on why it was judged idea-dense. Back to the overview.

Main speaker: Hank: 22 · John: 22

  • 2025-01-21 · John · Do Audiobooks Count As Reading? · Books & writing, letter vlog
    • Hoarse from recording his Everything Is Tuberculosis audiobook, John recalls how small the audiobook business was when Looking for Alaska came out 20 years ago and argues that audiobooks are definitely reading, for many people the best kind, since the point of reading is taking in words and ideas as transparently as possible. (00:00:56)
    • Why it is here: A sustained argument about what reading is, with reasons (transparency, retention, accessibility, reader as co-creator) and caveats about real differences.
  • 2025-01-28 · John · This Is Not Normal · Global development, letter vlog
    • John argues that the fall in child mortality since 1995, and centuries of health progress before it, were not natural or inevitable but came from human choices and sustained funding, including US-funded PEPFAR and the Global Fund, and warns that the new US administration's freeze on foreign aid threatens that progress. (00:02:55)
    • Why it is here: A data-dense argument about global health progress and its dependence on aid, pegged to a news event with life-and-death stakes.
  • 2025-02-07 · Hank · What Trump's Doing · US politics & society, letter vlog
    • Hank argues that the president's unilateral dismantling of USAID is illegal because Congress holds the power of the purse, that the real issue is whether the Constitution and the separation of powers still matter, and that Americans should refuse to believe Trump or Musk are more powerful than the Constitution. (00:00:00)
    • Why it is here: A focused civics argument on a live constitutional question, with an explicit reading of Trump's motives and a call to keep believing in the Constitution.
  • 2025-02-11 · John · What's at Stake · Global development, letter vlog
    • Drawing on his book research, John explains why interrupting months-long TB treatment is catastrophic, since untreated TB spreads and becomes drug-resistant, and argues that the US freeze on TB funding risks millions of deaths. He says only governments can respond at that scale, urges support for global health charities through the Project for Awesome, and rejects despair because TB deaths have halved in 25 years. (00:00:29)
    • Why it is here: A carefully argued public-health case with numbers, a stance on government versus philanthropy, and a hope-versus-despair conclusion.
  • 2025-02-18 · John · Gastrointestinal Hypermotility in Tuatara · Nerdfighteria, letter vlog
    • After a fake-topic title meant to keep casual viewers away, John says the 2025 Project for Awesome lifted him out of a discouraged, fearful month: it shows a strong us needs no them, that people together achieve far more than alone, and that community is what he is proudest of. (00:00:29)
    • Why it is here: A short sincere essay on despair, hope and collective action, framed by the P4A's running total and a joke title.
  • 2025-02-25 · John · EVERYTHING IS TUBERCULOSIS · Global development, reading
    • Reading the first chapter of his book Everything Is Tuberculosis, John traces tuberculosis through James Watt's dying son and his own great-uncle Stokes, and argues that TB, curable since the 1950s, still kills over a million people a year because the cure is where the disease is not. (00:04:14)
    • Why it is here: A dense essay with many sourced figures and a clear argument about TB as injustice and how imagining illness shapes who lives and dies.
  • 2025-02-28 · Hank · We Will Eradicate Measles · Health, explainer
    • Hank argues that measles can be eradicated because only humans catch it, explains why it is harder than smallpox (more infectious, two doses, less feared), and says its biggest advantage now is that we forgot, reading Roald Dahl's account of his daughter's death; he then condemns the halt of USAID funding and shares a script for calling Congress. (00:03:09)
    • Why it is here: A substantive explainer and argument: eradicability, vaccine coverage, forgetting as the obstacle, and a concrete civic script on USAID and executive orders.
  • 2025-03-07 · Hank · How Social Security Fraud Actually Works · US politics & society, explainer
    • Hank explains that there are not millions of very old Americans collecting Social Security: most fraud is overpayment, fighting it means bureaucracy for everyone to recover under 1% of benefits, and he condemns Trump and Musk for misleading America about its scale; he ends with a game of Connections. (00:03:53)
    • Why it is here: A careful, number-heavy explainer of how Social Security fraud works and a clear argument about the costs of fighting it and about misleading leaders.
  • 2025-04-04 · Hank · Morality · Philosophy & meaning, letter vlog
    • Hank argues that morality comes in three kinds: rules by which the powerful control others, arbitrary shared norms (like the taboo on curse words) that bind a society, and real morality about impact and care (taboos on slurs, gambling, scamming, lying) that every society needs; he thanks John and plugs John's book. (00:00:58)
    • Why it is here: A sustained argued essay with a clear three-part taxonomy and concrete positions on slurs, gambling, scamming and lying.
  • 2025-04-08 · John · DOGE Is Not Cutting Government Spending · US politics & society, explainer
    • John argues that despite DOGE's layoffs and cuts to foreign aid and science, US federal spending and the deficit are rising, because the items cut are tiny shares of the budget; the cuts are a political choice, not austerity. (00:00:00)
    • Why it is here: A clearly argued, number-driven correction of a widespread misconception about federal spending.
  • 2025-04-15 · John · Chatting with ... a U.S. Senator? · US politics & society, collab / interview
    • After a TB-advocacy trip to Washington, John interviews Senator Adam Schiff, who argues Congress is surrendering its power of the purse to the president yet stays optimistic; they discuss USAID cuts reversing progress against tuberculosis and the meaning of The Fault in Our Stars' title. (00:00:00)
    • Why it is here: A substantive interview on separation of powers, media fragmentation and the lasting harm of aid cuts, with concrete TB figures and both speakers' arguments.
  • 2025-04-25 · Hank · How We Form Opinions · US politics & society, explainer
    • Hank tells how smallpox variolation, brought to Boston by the enslaved Onesimus via Cotton Mather and to England by Lady Mary Wortley Montagu, met opposite reactions in the two places, and argues people judged it by how they felt about its advocates; he sees the same mechanism today with electric cars, vaccines and falling birth rates and argues for taboos against inflammatory fear of outsiders. (00:03:24)
    • Why it is here: A tightly argued essay on how group identity shapes belief, with historical evidence and contemporary examples.
  • 2025-05-06 · John · Health CARE: Thoughts from Lima · Global development, documentary visit
    • Reporting from a Partners In Health visit to Lima, John describes Peru's TB active case finding, PIH programs adopted by the Ministry of Health and the survivors Gladys and Brenda, and argues that what health care fundamentally needs is care for the person. (00:02:55)
    • Why it is here: A substantive TB-policy report (active case finding, blueprints for governments, health inequity) closing on a clearly argued point about care.
  • 2025-05-13 · John · I Have the BEST News · Global development, announcement
    • Six years after announcing his family's donation for a maternal center in Sierra Leone, John reports that the community raised the $20 million needed, that maternal mortality there fell from 1 in 17 to about 1 in 74, and that the Maternal Center of Excellence will finish construction in October and open in January; he argues that sustained attention and resources change things and asks for ongoing support. (00:01:27)
    • Why it is here: A substantive progress report: concrete numbers, an argument that system strengthening (not one fix) cut maternal deaths, and a case for long-term attention and funding.
    • Replies to: 2019-10-22 Why We're Donating $6,500,000
  • 2025-05-16 · Hank · No One Knows When They Don't Die · Health, letter vlog
    • Hank argues that people mostly never know when they didn't die: prevention (vaccines, the Clean Air Act, smoke detectors, lead bans, road and building safety, food safety) saves huge numbers of unknown people without stories or celebration, and our minds fail to see statistical deaths, as in maternal deaths in Sierra Leone, as catastrophes worth heroism. (00:00:00)
    • Why it is here: A tight, sincerely argued essay with many supporting numbers on why prevention is undervalued.
  • 2025-06-06 · Hank · The Secret Inside my MIT Commencement Speech · Everyday life, explainer
    • Hank explains that he wrote his MIT commencement speech from a survey of the graduating class, the way the brothers' work has been collaborative with its audience; in the speech he urges graduates to orient their curiosity toward the everyday problems of normal people and toward people, not only toward building tools. (00:00:00)
    • Why it is here: A substantive argued speech about curiosity, problems and people, plus a framing reflection on audience-collaborative creation.
  • 2025-06-10 · John · 90,000,000 Lives for $20 · Global development, letter vlog
    • John warns that US-led cuts to global health funding, now before Congress (PEPFAR cuts and a halved, re-matched Global Fund contribution), will reverse decades of progress against child mortality, TB and HIV, and asks viewers to call their representatives: about $20 a year per American for PEPFAR and the Global Fund, which saved 91 million lives, is the bargain of a lifetime. (00:01:27)
    • Why it is here: A data-dense, sincere mobilizing argument with life-and-death stakes and a concrete civic ask.
  • 2025-06-13 · Hank · Moving to Hope from Hopelessness (3 ways) · US politics & society, letter vlog
    • Angry and hopeless after deportation raids and protests in Los Angeles, Hank describes how he moves to hope: hopelessness is the less rational position, no one knows the future, and, after the Taoist idea of effortless action, focusing on care and humanizing people instead of shoving on a wall; he closes by announcing that the $50 million for the Maternal Center of Excellence has been raised. (00:00:00)
    • Why it is here: A sincere, argued essay on hope, political strategy, dehumanization and fear, with a concrete fundraising milestone as its closing evidence.
  • 2025-06-17 · John · My Religion · Philosophy & meaning, Q&A
    • Answering the questions he is most often asked about religion, John says he is an Episcopalian Christian who believes in God without needing to settle God's independent reality, centres his faith on forgiveness, radical hope and work for the marginalized, reads the Bible through an interpretive lens, struggles with the problem of evil, and does not worry about atheist Hank's soul because they are called by the same voice. (00:00:00)
    • Why it is here: A dense statement of John's theology and its ethical consequences, with clearly argued positions on scripture, evil, LGBTQ rights and religious pluralism.
  • 2025-06-20 · Hank · 'Influencer' Must Die. · Internet & YouTube, letter vlog
    • At VidCon 2025, where he was inducted into the VidCon Hall of Fame, Hank argues that being a YouTuber is a craft, not a business: he hates the advertising-industry word 'influencer', compares creators to musicians, and says the new part of the craft is being your own distribution, which is about empathy and building an audience. (00:00:38)
    • Why it is here: A short but argued essay on what online creators are and what to call them, with a clear analogy and a claim about what is new in the craft.
  • 2025-06-24 · John · Am I Cigarettes? · Internet & YouTube, letter vlog
    • John compares his compulsive use of the social internet to his years of smoking and Nicorette: he argues the social internet, though it builds community and gave him his life, is not a net positive for humanity, admits he cannot stop, and worries that by contributing to it he is not just smoking cigarettes but is cigarettes. (00:00:58)
    • Why it is here: A personal, carefully hedged argument about addiction and the social internet's costs, with a clear thesis and no offered solution.
  • 2025-06-27 · Hank · You’re Not Addicted to Content, You’re Starving for Information · Internet & YouTube, letter vlog
    • Answering John's 'Am I Cigarettes?', Hank argues the cigarette metaphor is dangerous because information, unlike nicotine, can be good; he proposes food instead: after millennia of scarcity we face an abundance of hyperpalatable information, personalized by platforms, which education alone will not fix, and he hopes simple stories exposing the manipulators will help, as with smoking. (00:01:27)
    • Why it is here: A carefully built argument with a clear alternative metaphor and specific claims about education, agency and cultural change.
    • Replies to: 2025-06-24 Am I Cigarettes?
  • 2025-07-04 · Hank · This Graph Changed My Life · US politics & society, letter vlog
    • Using Fox News comments calling climate change a hoax and a graph showing that under 10% of Americans are committed climate skeptics, Hank argues that the information ecosystem shows us the most extreme members of a group, a 'cable news fallacy' that makes us fight the wrong fight in despair. (00:00:59)
    • Why it is here: A sustained, carefully argued claim about how people misperceive out-groups, backed by survey numbers and a named coinage.
  • 2025-07-11 · Hank · The Ones Who Love Us · Philosophy & meaning, letter vlog
    • Revisiting Keanu Reeves's late-show answer to what happens when we die ('the ones who love us will miss us'), Hank says it answered an unanswerable question with an obviously true answer by reminding everyone they are just one person: what goes on after death is the whole story we are part of, and with the right flashlight we need not mourn missing it. (00:01:42)
    • Why it is here: A sincere, argued meditation on mortality and ego, turning thoughts about death outward.
  • 2025-07-22 · John · At Least There Are Trees · Science & nature, letter vlog
    • Walking in a 12,000-year-old forest, John says trees console him: plants make up most of Earth's biomass, early trees once caused a mass extinction, and ginkgos predate us by ages, yet trees remind him that humans, the only species to name the ginkgo, are participants in life on Earth, not observers. A P.S. plugs a DFTBA shirt whose proceeds go to the Nature Conservancy. (00:00:00)
    • Why it is here: A sincere, argued essay mixing natural-history facts with a claim about humans' place among living things.
  • 2025-07-25 · Hank · The Molecule that Changed Everything · Science & nature, letter vlog
    • Replying to John's 'At Least There Are Trees', Hank explains how trees caused the Devonian mass extinction: lignin, which almost nothing could break down, piled up in swamps; tree-released phosphorus fed algae blooms that stripped oceans of oxygen; those buried trees became coal that powered the Industrial Revolution and now climate change. Unlike trees, humans can choose to stop a second apocalypse. (00:00:37)
    • Why it is here: A sincere, structured science explainer correcting his earlier account, ending in an argued claim about human agency on climate.
    • Replies to: 2025-07-22 At Least There Are Trees
  • 2025-08-15 · Hank · What Trump is Doing to Universities · US politics & society, explainer
    • Hank places the Trump administration's pressure on universities (withheld grants, a 15% cap on research overhead, visa limits) in a long pattern of authoritarian attacks on universities, argues universities are a ready-made out-group and a threat to a narcissist's self-image, and explains why the decentralised US system should prove more resilient. (00:00:00)
    • Why it is here: A carefully argued political analysis with a concrete policy explainer and a closing value judgement that coercing institutions with taxpayer money is un-American.
  • 2025-09-12 · Hank · This Might Actually be Happening · Science & nature, explainer
    • Hank explains that Perseverance found iron and sulfur chemistry in a Jezero Crater mudstone that is hard to explain without past life on Mars, surveys earlier Mars evidence, the tests that could settle it and what a yes would mean, and argues that big scientific claims become consensus slowly, so even a huge discovery can feel anticlimactic. (00:04:17)
    • Why it is here: A carefully argued science explainer: the claims about the evidence, the tests and how scientific consensus forms are the substance.
  • 2025-09-23 · John · Why Can't I Take My Meds? · Health, letter vlog
    • John explains why so many people, himself included, fail to take medication as prescribed (cost, feeling fine, side effects, stigma around a 'natural' unmedicated state, depression), argues that natural is not what humans are going for, and says the one strategy shown to work is tying medication to an existing daily habit. (00:00:29)
    • Why it is here: A sincere, argued explainer mixing research figures with John's own struggle with his pills; the 'natural is not the goal' argument and the habit advice carry real ideas.
  • 2025-10-01 · John · Real Reasons for Hope · Global development, letter vlog
    • John offers two under-reported reasons for hope: the cost of curing multidrug-resistant TB has fallen from about $30,000 to under $300 through decades of advocacy, and maternal mortality in Sierra Leone has dropped by over 60% in ten years; he argues that such progress is slow, unglamorous and real, and that today is the middle of the story, not the end. (00:00:29)
    • Why it is here: A clearly argued case, with figures, that activism works slowly and that hope is justified without denying reasons for outrage.
  • 2025-10-02 · Hank · You are Probably Underestimating Jane Goodall’s Impact · Science & nature, explainer
    • Hank argues that Jane Goodall was a revolutionary scientist: by staying, watching and refusing the anti-anthropomorphism rules of animal science, she showed that the tools built to make science objective had hidden animal culture and emotion, and that humans are not alone on this planet. (00:01:27)
    • Why it is here: A carefully argued essay on what science is, how its tools and norms can hide truth, and how Goodall's work exposed and corrected that.
  • 2025-10-03 · John · Is It Time to Retire? · Nerdfighteria, letter vlog
    • John asks when he should retire from YouTube: as with athletes, of whom it is said the game tells you when you're done, YouTube careers tend to be short; at 48 he is not sure he wants to make a video every Tuesday at 58 or 68 and would like to retire to writing someday, but he values Nerdfighteria and his project with Hank, and he asks viewers whether to wait to know or end Vlogbrothers intentionally. (00:01:23)
    • Why it is here: A sincere, personal reflection on ending the channel, with clear positions on creative discipline, the community and the brothers' shared project.
  • 2025-10-06 · Hank · The Web is Going to Die · Internet & YouTube, letter vlog
    • In a Thoughts From Places video from Garnet, a Montana ghost town, Hank argues that ghost towns are rare because people and places bind together, but that the internet is full of them: platforms like Vine, Myspace and Google+ were abandoned, the web itself is becoming a ghost town, and one day even Twitter, Facebook, Instagram and this channel will be too. (00:02:22)
    • Why it is here: A sincere argued essay that ties the history of Montana ghost towns to network effects and the fragility of online places.
    • Replies to: 2025-10-03 Is It Time to Retire?
  • 2025-10-07 · John · Luck vs. Work vs. Skill vs. Privilege · Books & writing, letter vlog
    • John weighs what drove his success as a writer: structural advantages, real but limited talent, failures nobody sees, the luck of Nerdfighteria and of The Fault in Our Stars' timing, and hard work; he argues these cannot be separated and that deserving is the wrong framework, since what people do deserve is to love, be loved and be treated as full human beings. (00:00:29)
    • Why it is here: A carefully argued personal essay on luck, privilege, talent and desert, with concrete career evidence and a clear conclusion.
    • Replies to: 2025-10-06 The Web is Going to Die
  • 2025-10-17 · Hank · We Never Know What Anything Means · History & curiosities, letter vlog
    • Using a new Complexly series, Endlings, whose first episode shows that the telegraph helped drive the passenger pigeon extinct, Hank argues that we never know what anything means: stories about the future fail beyond a short horizon, AI's biggest effects are as unforeseeable as the telegraph's were, and the future just grows in ways nobody intends. (00:00:00)
    • Why it is here: A sincere argued essay with a clear thesis, a historical case and explicit near-term AI predictions.
  • 2025-10-21 · John · Is Book Publishing Dying? An Author's Perspective · Books & writing, letter vlog
    • John asks whether book publishing is in structural decline: it is a tiny business and sales are falling as attention shifts and books lose their edge as a cheap entertainment deal, but people still read because books add value, and he argues books, a deeper entertainment the reader co-creates, will not go away. He closes by asking viewers to make art for the P4A Nerdfighter Art Perk. (00:02:28)
    • Why it is here: A sustained, argued essay with data about reading and publishing and a clear position on why books will survive.
  • 2025-10-31 · Hank · We Did It… · Global development, letter vlog
    • Answering people who say John only cares about tuberculosis, Hank argues that problems have size, difficulty and visibility, and that big, solvable problems persist mainly because they lack visibility, which is why John's focus on TB is his genius; he tells how retitling John's Philippines video rescued its views, and announces the ribbon-cutting of the Maternal Center of Excellence in Sierra Leone that the community helped fund. (00:01:27)
    • Why it is here: A clearly argued model of why some problems go unsolved (the visibility of a problem), with checkable cost comparisons and facts about the new hospital.
  • 2025-11-04 · John · The Real Question · Global development, letter vlog
    • Back from TB meetings in the Philippines, John tells Hank that his tuberculosis focus is a path into a larger question, why suffering is so unjustly distributed; funding gaps mean people go untreated, and he argues we fail to build systems reflecting that all human lives have equal value, making the injustice a shared fault, including his own. (00:03:24)
    • Why it is here: A sincere, clearly argued moral essay with checkable TB figures and a direct claim about shared responsibility for global health injustice.
    • Replies to: 2025-10-31 We Did It…
  • 2025-11-10 · Hank · My Cancer Treatment was Not Cutting Edge · Health, letter vlog
    • Replying to John's claim that he got cutting-edge curative cancer therapy, Hank explains that his Hodgkin lymphoma chemo dates from the late 1970s, but that careful, slow research added anti-nausea care and cut the doses, making treatment better and cheaper. He argues that solutions must both exist and be justly distributed. (00:00:58)
    • Why it is here: A clear explainer of how cancer treatment improves without new drugs: nausea control, research that cut doses, and why governments should fund it.
    • Replies to: 2025-11-04 The Real Question
  • 2025-11-13 · John · Fighting TB in Kids: A Discussion with Doctors without Borders · Global development, collab / interview
    • In a livestream panel on tuberculosis in children, John and guests from Doctors Without Borders (survivor Ani Herna Sari, Mozambique pediatrician Dr. Natalia, Sierra Leone TB program manager Dr. Mariama and MSF adviser Cathy Hewison) discuss misdiagnosis, missing child-specific tests and formulations, weak health systems and aid cuts; John concludes that protecting kids from TB is a question of prioritization and political will. (00:00:00)
    • Why it is here: A dense, sincere expert discussion with many checkable figures on pediatric TB diagnosis, prevention and funding; little humor.
  • 2025-11-14 · Hank · The End of The Penny (and of Congress??) · US politics & society, letter vlog
    • Marking the likely end of the US penny, which Trump's Treasury stopped minting by ruling the necessary number zero, Hank tells John that Obama thought it needed Congress; he argues Congress has given its power away, mainly through filibuster paralysis, leaving presidents to act alone, and warns this invites an autocrat. (00:02:24)
    • Why it is here: A real argument about the separation of powers and congressional weakness, using the penny as its way in.
  • 2025-11-25 · John · Poverty Is Expensive · Global development, story
    • John tells how Henry Reider and his mother Isatu, invited to the Union tuberculosis conference in Copenhagen, waited weeks in Ghana for Danish visas and Isatu was denied; he argues that TB and visa injustice show poverty is expensive and that visas shape who is heard about TB, which persists because we fail to treat all humans as equal. (00:02:26)
    • Why it is here: A sincere argued story: poverty costs time and money, visa rules decide whose voices shape global health, and TB is a symptom of unequal systems.
  • 2025-12-02 · John · The Meaning of Life with Hank and John · Philosophy & meaning, Q&A
    • On a Question Tuesday filmed on the set of Ask Hank Anything, John and Hank answer the meaning of life: John says it is being in relationship with others and paying attention, Hank finds meaning in emergent complexity, in something being better than nothing, and in cultivating interest; they agree that what we do with our attention is what we do with our lives. (00:01:58)
    • Why it is here: Both brothers state their own answers to the meaning of life and reach a shared view on attention, amid banter.
  • 2025-12-19 · Hank · My Big 2026 Prediction is...Not Fun · US politics & society, letter vlog
    • In the brothers' last video of 2025, Hank asks viewers to fill out the 2025 Nerdfighteria Census, shows his 2026 bingo card, and predicts that AI, loved by the billionaire side of Trump's coalition and disliked by its populist base, has a good chance of doing a lot of damage to that coalition in 2026. (00:01:57)
    • Why it is here: An argued political forecast about AI and Trump's populist-elite coalition, plus a reasoned case for why the Census matters to the community.
